Application filed February 14, 1927., serial No. 168,187.

This invention relates to a furnace-cleaning apparatus, and one objectof the invention is to provide an apparatus of this character, theelements of which may be mountedupon a truck and thereby from one placeto another.

Another object of the invention is to so arrange the elements of thecleaning a paeasily transported ratus upon a platform forming part 0 thetruck that they will be entirely disposed within the confines of theplatform and thereby eleminate danger of their being damaged by strikingobstructions while the truck is being moved from one place to another.

Another object of the invention is to cause thejweight to be welldistributed over the plalzlform and thereby provide a balanced loaAnother object of the invention is to-prevent the elements of thecleaning apparatus from being damaged by vibration when the apparatus isin use. j

The improved furnace-cleaning apparatus is illustrated intheaccompanying drawings, wherein v Fi re 1 is a view showing the apparatusin si e elevation;

Fig. 2 is a top plan view of the same;

Fig. 3 is a sectionalview through the dust collectgir 'illustrating themanner of releasably connectin sections of the hose forming'a portion 0the .apparatus. V

The furnace-cleaning apparatus constitutin the subject-matter of thisinvention inclu es a truck which is of a conventional construction andindicated in general by the numeral 1. This truck is provided with a 1platform 2 which extends'rearwardly from the driverscab 3 and is formedwith aflatuninterrupted upper surface. The. platform is rectangular inshape and preferably of greater length tgian width. While the vehicleconstituting. the portable carrier has been illustrated asan automobiletruck, it

will be understood that any vehicle including a platform correspondingto the platform 2. maybe employedby the numeral;. 4, a fan operatingmotor 5 which operates the fan through the medium of a belt 6, a dustcollector 7, a removable dust receptacle or bag 8 and a hose 9 leadingfrom the inlet of the suction fan 4. By referring to Fig. 1, it will beseen that the motor 5 is mounted upon the platform2 adjacent its forwardend and at one side thereof-and the fan 4 is firmly secured upon theplatform rearwardly of the 'motor 5 and preferably above the rear axleof the truck. The dust collector 7 is disposed adjacent the front of theplatform at the opposite side thereof from the motor 5 and consists of acasing 10 which is circular in top plan and is partially closed at itsupper end by an annular flange or head 11. The lower portion 12 of thecasing tapers downwardly and terminates in a reduced outlet spout 13adapted to be passed through an opening formed in theplatform2 andproject below the platform" a sufficient distance to have the closurecap 14 applied thereto when the apparatus is not 1n use or the neck ofthe dust receptacle or sack 8 connected therewith. The sack 8 is formedof fabric and has its neck firmly secured about a metal ring 15 of suchinternal diameter that it may fit snugly upon the projecting lower endportion of the neck 13. Internal bayonet slots 16 are formed in the ringand spaced from each other circumferentially of the ring for receptionof the pins 17 which project radially from the neck. It will thus beseen'that the receptacle ma be firmly 'engaged with the neck of the coector but may be easily removed when the truck is to be moved or thereceptacle becomes filled and needs to be emptied. In its upper portionthe collector carries an annular air deflector 18 v which extendsdownwardly from the head 11 and is intended to im art. a whirling motionto dust laden air w ich enters the casing air-passes withoutcarryingthe'dust with The pipe 19 extends diagonally across t e platform andterminatesin 'a. downwardly curved free end portion 20 disposed abovethe outletneck 21 of the fan 4 and connected with the outlet neck of thefan by a shortsection of flexible tubing 22, the ends ofwhich aresecurely butremovably fastened to the adjacent ends of the pipe andoutlet neck. By having the tube 22 formed of flexible ma- 'terial, suchas reinforced fabric or the like,

the collector will not-be affected by vibration suction fan; This fan isofa .conventiona construction and includes the usual shaft 23 carrying apulley 'wheel 24 about which passes the belt 6 which is engaged with thepulley wheel 25 carried by the shaft 26 ofthe motor 5. The pipe 9 orhose asitmay be called has voneend attached to the'inlet of the suctionfan. This hose is of suflicient length'to reach from the truck to thefurnace to be cleaned and is preferably formed of a number of sections27 which may be of an desired length but are preferably six feet I. ongand twelve inches in diameter;

These sections are placed in end to end engagement with each other andhave their ad'- Jacent ends releasably connected so that they may betaken apart or additional sections added if necessary".. As a preferredmeans forconnecting adjoining sections, I employ asplit s1eeve 28 ofsufiicient length to overlap the adjacent ends of the sections and ofsuflicient diameter to fit snu Stra ly about them. 29 are passed aboutthe .end portions of t e couplin will cause t e ing engagement with the.hose sections. The hose may be coiled and placed upon the platplatform,

.will be very well balanced and no parts will project from the sides orends of the platfornn-as shown in Fig. 1, when not in use and add tionalpipe-sections ma be piled upon the'platformrearwardly 'o the collectorif so desired. By having the elements forming the cleaning apparatus.mounted upon the as shown inFigs. 1 and 2, the load Therefore, they willnot be liable to to be struck when the truck is-in motion and tudinallyupon the latform to collector and the ust bag'is removed and sleeve andwhen tightened eeve'to be held in tight binddamaged. When the deviceisin operation,

the hose is extended from the truck into the cellar in which is locatedthe furnace to be cleaned and the inner end of the hose applied tovarious portions of the furnace or pipes from whichit is desired toremove soot. The suction of the fan draws the soot through the hose intothe fan housing and expels it through the ipe 19 into the dust collectorthrough whic it passes intothe bag 8. When the bag is filled, itcan beeasily removed and a new one substituted while the filled one is beingemptied.- After the furnace has been 4 cleaned, the hose is againcoiledupon the platform and surplus sections placed lon t erear 0ft emay be placedin the cab'of the truck or 7 the side of the body near thetop thereof,'a
